Locky: the encryptor taking the world by storm

In February 2016, the Internet was shaken by an epidemic caused by the new ransomware Trojan Locky (detected by Kaspersky Lab products as Trojan-Ransom.Win32.Locky). The Trojan has been actively propagating up to the present day. Kaspersky Lab products have reported attempts to infect users with the Trojan in 114 countries around the world.

Analysis of the samples has shown that this Trojan is a brand new ransomware threat, written from scratch. So, what is Locky, and how can we protect against it?

Propagation

In order to spread the Trojan, cybercriminals sent out mass mailings with malicious loaders attached to spam messages.

Initially, the malicious spam messages contained an attached DOC file with a macro that downloaded the Locky Trojan from a remote server and executed it. Continue reading

Meet Bond, Microsoft Bond – A New Data Serialization Framework

Microsoft Bond is a new serialization framework for schematized data created by Microsoft.

Let’s recap where data serialization is used most:

Data persistence in files, streams, NoSQL, and BigData.
Data transmission in networks, IPC, etc.
Commonly, these applications have to deal with schematized data, where schema means:

Structure: hierarchy, relations, order.
Semantic: age in number of years since born.

Actually, any data has schema even if it is implicitly defined or supported by your programming language out-of-box. When it comes to complex data structures, we end up writing supporting data transfer objects (DTOs) and code responsible for IO, often in different languages. As soon as it grows and evolves, it quickly becomes a nightmare to maintain all these pieces. Here is where the serialization frameworks win the game. Continue reading

Windows 10 Development: Addressing Old Problems And Opening New Doors For Developers

I hope readers will pardon the carpentry pun, but Windows 10 is just around the corner, and Redmond’s new OS will create many possibilities for software and hardware developers.

Windows 10 represents a departure from Microsoft’s traditional OS strategy. It’s not just a new operating system, it’s an automatic and free update for millions of Windows 8.1 devices. It’s also designed to address a number of user complaints related to the Windows 8.x UI (formerly known as Metro design language or Metro UI). The changes aren’t just skin deep, as Windows 10 is not a mere redesign with a new UI and fancier apps; it might even mark the start of a new era for Microsoft, and in this post I will explain why.

First, let’s take a look at what Microsoft is trying to do in terms of addressing Windows 8.x foibles. After all, that’s what Windows 10 is all about, at least on the surface. Continue reading
